matlab Write a statement to shift the contents of array sampleReadings $1$ position to the left. Assign the rightmost element with $-1.$

Ex: If sampleReadings is $[12,85,43],$ then sampleReadings becomes $[85,43,-1]$ function sampleReadings $=$ ShiftArrayLeft$($sampleReadings$)$

$\%$ sampleReading: Array of sensor readings

$\%$ Write a statement to shift the array contents $1$ position to the left

$\%$ Assign the rightmost element with $-1$

sampleReadings $=0$;

end Check if ShiftArrayLeft$([12,85,43])$ becomes $[85,43,-1]$ Check if ShiftArrayLeft$([100,-4,-77,12,25])$ becomes $[-4,-77,12,25,-1]$
